FUEL-MXNG DEVICE.

Application filed April 8,

The present invention relates to improvements in fuel mixing devices for use in conjunction with internal combustion engines, and has for its principal object to provide a simple and efficient device which may be readily and easily installed between the in` take manifold and the inlet to the cylinders of the internal combustion engines for the purpose of breaking up the gas into fine particles before entering the cylinders of the engine.

One of the iinportantobjects of the present invention is to provide a device of the above mentioned character which is of such construction as to be self adjustable so that the proper amount of gas will be admitted to the cylinders of the internal combustion en gines depending upon the speed at which the motor is operating.

A further object of the invention is to provide a device ofthe above mentioned cliaractor which will save considerable expense in the operation of an internal combustion engine by reducing the gas consumption to .a minimum, the device being at all times positive and efficient in its operation.

A still further object is to provide a device of the above mentioned character which is simple in construction, inexpensive, strong `and durable and further well adapted to the purpose for which it is designed.

Other objects andadvantages of the invention will become apparent during the course of the following description taken in connection with the accompanying drawing.

In the accompanying drawing forming a.

part ofV this application and in whichflike numerals designate like parts throughout the several views:

Figure 1 `is a side elevation of the fuel mixing device embodying my invention showing the same installed in an internal combustion engine.

Figure 2 is .a vertical sectional view through the device, and

Figure 3 is a top plan view thereof.

In the drawing' wherein for the purpose of illustration is shown the preferred embodiment of the invention, the immoral 1 designates generally my fuel mixing device, the same comprising the split ring 2 which is provided at its lower edge with the annular flange 3 whereby the same may be properly positioned between the upper end of the intake manifold A and the gas inlet B of an internal combustion engine designated by 1926. Serial No. 100,594.

the numeral 3. The manner in which the device is installed in an internal combustion engine is clearly illustrated in Figure l.

A spring supporting stem 4 is formed by taking four elongated strands of copper wire and twisting the saine around one another for the greater portion of their length. The lower ends of. the wire are disposed in diverging relation and are secured to the inner face of the split ring 2 adjacent the bot? tom thereof in any appropriate manner, the diverging lower portion of the lwires being designated by the numeral 5 with reference more particularly to Figure 2. The upper ends. of the wires adjacent the twisted stem portion 5 are also disposed outwardly in di` verging' relation as illustrated at 6 to provide a stop, the purpose of which will be hereinafter more fully described. In this manner, the stem 4C will extend centrally from the ring e.

A. volute spring 7 is attached at its base or -open end to the inner face of the ring 2 adjacent the lower edge thereof and this volute spring extends upwardly above the ring and surrounds the intermediate portion of. the stem 4, a suitable collar 8 being carried by the upper smaller end of the volute spring and the same being adapted to slide along the stem t in the manner to be hereinafter more fully described.

A complementary volute spring 9 is attached at its base or open end portion to the upper portion of the inner face of the ring 2 and this additional or outer volute spring 9 also surrounds the stem l and carries at its smaller upper end the collar pin which is adapted also for slidable movement along the stein 4 in the manner to be presently apparent. As is clearly illustrated in the drawing, with reference more particularly to Figure 2, these volute springs are arranged in spaced relation with respect to each other, and are fully turned or constructed in such a manner as to cause one of the springs to be disposed in a lefthand direction, and the other in a right hand direction.

rllie. operation of my improved fuel miie ing device be briefly stated as follows. rlhe device is attached or installed in the inaiiiier shown in Figure l so that the volute springs extend into the inlet opening B of the cylinders of the internal combustion engine C andnorinally the volute springs are disposed as shown in Figure 2. Should the motor run at a speed of approximately th ee hundred R. l). M., the suction will not be sullicient to cause the expansion of the volute springs 7 and 9, and consequently, the gas which passes upwardly through the intake manifold A will enter the device and will pass through the inner and outer volute springs 7 and 9 respectively before the gas enters the motor, thus causing the gas to be broken up into fine particles, and thereby effecting the ready combustion of the mir;- ture in the respective cylinders, thus affording easy and quick starting of t-he motor.

Simultaneously with the increase in the speed of the motor, the suction will become greater, and as a result the volute springs will be expanded thus increasing the space between each of the turns of the springs to permit a wider opening` for the passage of the gas therethrough.

The expansion of the volute springs caused by the increase in the speed and suction will naturally cause the collars 8 and 10 of the inner and outer volute springs 7 and 9 respectively to travel upwardly on the stem 4; and the outwardly disposed upper ends of the wires or rods from which the stem s formed will prevent the displacement of the collars from the stem as is readily obvious from the construction shown in the drawing.

Furthermore, these outwardly disposed ends 6 of the several wires or rods will serve for the purpose of preheating or vaporizing the gases as the same enter the inlet B.

It will thus be seen from the foregoing description that l have provided a fuel mixing device which will be at all times positive and efficient in carrying out the purpose for which it is designed and will be furthermore self adjustable to compensate for the speed at which the motor is traveling.

' lVhile I have shown the preferred embodiment of my invention it is to be understood that minor changes in the size, shape and arrangement of parts may be resorted to without departing from the spirit and scope of the appended claim.

Having thus described the invention, what l claim as new and desire to secure by Letters Patent is A fuel mining device comprising a supporting ring, inner and outer frusto conical springs having their base portions connected with said ring and having their aplces spaced apart and in longitudinal alignment with each other, and a guide extending through and beyond said apices, the apices of the conical springs being freely mounted for movement on the guide, said guide being formed from a plurality of wires twisted together to provide a rigid stem, the wires at one end being connected with said ring and being formed into stops at their opposite ends.

In testimony whereof I aliix my signature.
